hi josh,
thanks for the advise. it's the "FIREWALL" thing that
don't allow my FreeBSD to access the Internet Sharing
in the Windows XP. Now, its ok already. I just
unchecked the option that "Restricts IP hosts from
Internet (external) to access the Internet Sharing
Machine" or something like that. Now its working. It
really is not a problem with my FreeBSD LAN card or
other configurations. It's the WindowsXP trick!
